SPRAYING-NOZZLE.

Specification of Letters Patent.

Patented Dec. 14, 1920.

Application filed January 28, 1918. Serial No. 214,106.

To all whom it may concern:

Be it known that I, NORMAN V. HALSEY, a citizen of the United States, residing at New York, county of New York, and State of New York have invented certain new and useful improvements in Spraying- Nozzles, fully described and represented in the following specification and the accompanying drawings, forming a part of the same.

This invention relates to nozzles of the kind provided with spraying devices which are rotated, to spray the water or other liquid, by mechanical means or by the force of the water or other liquid as it is issuing from the nozzle. These spraying devices consist of a hub having suitably shaped vanes radiating therefrom, this hub being so mounted as to be free to rotate on a suitable support.

Heretofore these spraying devlccs have been made either by casting them in a single piece from suitable metal, or by securing the vanes to the hub by soldering, riveting, or in other suitable ways.

The improvements of the present invention have for their object the provision of a spraying device having all of the advantages of both of these types of spraying devices, with none of their disadvantages, and

having also other additional advantages, 1n-

cluding that of economy in cost of materials and manufacture.

In the accompanying drawing- Figure 1 is a side view of part of a pipe equipped with a spraying device embodying the present invention;

Fig. 2 is a section of the same on the line 2 of Fig. 1; Fig. 3 is a plan view of a metal blank. from which the spraying devlce is made,

and

Figs. 4 and 5 are details of the spraying; device, illustrating the method of forming from the blank of Fig. 3.

Referring to said drawing, 1 represents a pipe provided with a bracket 2 in line with its nozzle 3 for supporting a spraying device 4 in line with the nozzle opening, so that it will be rotated or spun by the force of the water issuing from said nozzle. This spraying device consists of a tubular hub 5 and vanes 6 radiating therefrom and deflected or bent horizontally, as at 7, to

receive the impact of the water issuing from nozzle 3. The spraying device also ncludes a barrel 8 having a central open- 111g for receiving a pin 9 secured to the bracket 2 and on which the spraying device is free to spin or rotate.

The hub 5 and vanes 6 of this spraying devlce are integral, being formed from a single piece of sheet metal shown in Fig. 3. This sheet of metal (preferably brass) is folded or bent inwardly on the lines 10, radiating from the center of the blank, to form the hub portion of the spraying device and to provide four vane sections A, B, O, D, each of which is double the area of the vane and is folded downwardly on itself, on the line 11, to form the vanes 6. The advantage of thus folding each vane section of metal downwardly, is that there is provided an unbroken upper edge against which the water or other liquid impacts as it issues from nozzle 3. The blank of Fig. 3 then assumes the position or condition shown in Fig. &. The point of barrel 8 is then introduced into the space where the inner ends of the vanes converge or meet and the barrel then forced upwardly into the position shown in Fig. 1. In assuming this position, the barrel 8 will spread the two metal layers of each vane slightly apart, at their inner ends to make room for the barrel and provide the hub 5. When barrel 8 has been driven home to the position shown in Fig. 1, the metal of hub 5 ,may, if necessary, be forced into intimate ;contact with it, by the use of suitable tools ifor that purpose, or the hub 5 and barrel 8 !may be otherwise secured together.

Before or after the barrel 8 has been -'';forced into position in the spraying device,

the lower ends of the vanes will be bent in a horizontal direction, as at 7.

The barrel 8 is, as shown in Fig. 1, provided with a vertical central opening for receiving the pin 9 secured to bracket 2. Pin 9 supports the spraying device in line with nozzle opening 3 and permits it to be freely rotating under the impact of the water issuing from said nozzle.

It will be obvious that the spraying device is of light weight and yet, because of its integrality and the double thickness of its vanes, of great strength. It will also be obvious that, being seamless, there is no liability of grease and other objectionable substances collecting upon it, and because it is integral there is no liability of any of its vanes Working loose from its hub. It has also the great advantage over prior art spraying devices of economy in cost of materials and manufacture.

Although the spraying device shown and described has four vanes, it will of course be understood that the number of vanes may be varied without departing from the invention.

What is claimed is:

-1. A spraying device comprising a plurality of integral vanes of sheet metal bent inwardly and downwardly to form a tubular barrel-receiving hub in line with the vanes.

2. A spraying device comprising a plurality of integral vanes of sheet metal, each vane consisting of a section of such metal folded upon itself.

3. A spraying device comprising a hub and a plurality of vanes radiating therefrom, said hub and vanes being integral and of sheet metal, and each vane consistingof a section of such metal folded upon itself.

4;. A spraying device comprising a plurality of integral vanes of sheet metal, each vane consisting of a section of such metal folded downwardly upon itself to provide an unbroken upper edge.

5. A spraying device comprising a hub and a plurality of vanes radiating therefrom, said hub and vanes being integral and of sheet metal, and each vane consisting of a section of such metal folded downwardly upon itself to provide an unbroken upper edge.

In testimony whereof,

I have hereunto set my hand.

NORMAN W. HALSEY.
